The Voice Print Technology

This week, we all did a presentation on a topic of our choice by “Applying Waves & Sound to Design”. I talked about voice print and how it related to our unit, the main uses of it, the impacts it has on society, careers involved, and the new research being done to improve this technology. I wanted to further explain voice printing and give you links if you are interested in discovering the many sides to the voice print technology.

What is voice print? 

Voice print can be defined as a set of measurable characteristics of a human voice that uniquely identifies an individual. 

In accurate voice printing, frequencies and amplitudes are measured, factoring in intensity, pitch and tone.

The voice print technology is used for many more different things in our modern world, but the list could go on and on. Since, the voice print technology is found almost anywhere, it has positive and negative impacts to our society. Voice printing is a very useful tool to help identify callers as suspected fraudsters, but it is not impossible to get past the system, if their voice printing technology is not up to date.

If you are interested in voice print technology and want to explore it in the future, to maintain and research about it, there are different majors that can lead to a career in the voice print technology. Click here!

Research is continuously being done for this technology, people around the world are finding new ways to use it. Watch this really cool video where a 3-D voice print of Obama’s voice is played.
